[Users] Error in a function

[Roland Haas]

Hello Erik,

there is not quite enough information provided in the code fragment you
are providing to tell for sure what is going on.

Would you be able to create a dummy thorn that shows the issue, then
include a tar file of the whole thorn (including source, header, ccl
files) as an attachment to the email?

A blind guess though: I have seem strange syntax errors being caused by
missing semicolons in header files so I would double check those. You
also do not really need to (nor should you to tell the truth) declare
"void Initial_Setup(CCTK_ARGUMENTS);" in ID.h since the Cactus flesh
will automatically include prototypes like that for all scheduled
functions in the cctk_Arguments.h file it creates for your thorn.

Yours,
Roland
